Specification of Letters Patent.

Application filed August 15, 1907. Serial No. 888,680.

To all whom it may concern:

Be it known that I, ANNA C. CLARKE, a' citizen of the United States,residing at Scranton, county of Lackawanna, State of Pennsylvania, haveinvented certain new and useful Improvements in Sewage Systerms forRailway-Cars; and I do hereby declare'the followin to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

The invention relates to apparatus for the disposal of sewage and thelike from railway cars, and is intendedto be ap lied in connection withwater closets, sinks, avatories and the like, for the purpose ofcatching and retaining the discharge therefrom to prevent such dischargebeing deposited on the right of way, as is thepresent practice on mostrailroads.

The deposition of refuse from railway cars onthe right of way and moreespecially where the matter consists of human excreta, is undoubtedlythe source of contamination of many water sup lies and is also apositive menace to the heath of passengers on the cars, as well as thatof persons working upon or living adjacent to the right of way.

The present invention has for its object to provide means for catching,and retaining such refuse matter in a propriate ree ceptacles orreservoirs carrie by the cars, from which said matter may be dischargedat appropriate places, the reservoirs being either stationary orremovable, and having appropriate connections with the waterclosets,lavatories or sinks on the cars and, when the reservoirs are removable,suitable flexible connections between the same and the bowl of thecloset, lavatory or sink, as the case may be, are provided. Thereservoir is also preferably provided with a vent pipe or stack which,when the reservoir is removable, is also provided with a flexible andremovable coupling or connection with the reservoir.

In the accompanying drawings, Figure 1 shows the end of a car in sideelevation, partlybroken away to illustrate the invention as applied to awater closet; Fig. 2 is a side elevation of a convenient form ofreservoir. Fig. 3 is a longitudinal section through the same. Fig. 4 1sa transverse section of the reservoir showing also a convenient meansfor removably securing the same in place on the car.

The invention has been shown in connection with a water closet merely bway of illustration or example, and it is to e understood that it islikewise applicable to lavator1es, sinks, urinals and the like, and thatthe, claims are intended to be interpreted accordingly.

In the drawings, a indicates the hop er or bowl of a water closet, whichmay e of any preferred form provided with the usual trap to prevent theescape of ases or efliuvia into the apartment. Suspen ed from the bodyof the car and preferably in the most convenient and accessible locationis a tank or reservoir 6, adapted to be connected with the outlet of thecloset bowl. In its preferred form, thelreservoir is a cylinder of metalclosed at each end by re movable heads 71, held in waterand gas tightcontact with the cylinder ends by means of yokes j and set screws 70. Ifdesired, one end of the cylinder may be perma'nently closed and theother provided with a removable head.

Near one end, the tank 6 is provided with a nipple 0 adapted to, receivea tubular connection d attached at its other end to the outlet of thebowl a. If tank 6 is removably secured to the car, connection d mayconveniently be made of a section of rubber hose or piping, one end ofwhich is passed into niple 0 and through a rubber packing e to ef-. ecta gas tight fit. If the tank is permanently attached to the car, it maybe connected with the bowl by any suitable permanent coupling or piping.

In order to properly vent tank I), it is connected with a stack or pipeZ, which is preferably carried up above the car roof so that air andnoxious gases may escape from the tank, without annoying or endangeringthe passengers. With a permanently attached tank, said stack may berigidly attached thereto, but when the tank is intended to be removed,the stack is connected therewith by a short section of rubber piping orhose g threaded through a nipple h and packed by a rubber gasket 7.

In order to removably attach the tank I) to the car, any appropriatesupports or suspending means may be provided, a simple and efficientapparatus for the purpose consisting of pendent brackets n, secured tothe under side of the car body, each having a horizontal bottom member10 and a hinged Patented May 17,1910.

outer side member 0, adapted to be swung down to permit the insertion orremoval of the tank, and when turned up to be locked osition by a setscrew an nut s. The is held firmly in position agamst lateral movementby the bracket sides and against endwise movement by lugs m on thebottom of the tank which embrace the horizontal members of the brackets.t

The operation and utility of the invent on will be apparent from theforegoing description. Matter deposited in the closet, urinal, lavatoryor sink on the car'will be carried directly into the tank band retainedtherein until the car reaches the proger'place for discharging thecontents of t discharge being efiected either'by removing the tank as awhole and replacing it byanother, or by opening one of the heads orclosures and ermitting the matter to flow out.

The cylindrical form of the tank permits it to be readily cleansed byflush ng, and all of the parts of the apparatus belng capable ofthorough cleansing and dismtectmg, a

a thorough sanitary condition of the same may be maintained.

In order to facilitate the emptying of the tank without removing theheads when said tank is *provided with removable heads, the inlet nipple0 may be employed as a discharge when' the tank itself is removable. Onthe other hand, when it is desired to dis-' charge the contents of thetank when the latter is stationary and more particularly when it is notprovided with removable ends, a

e tank, such 2, may be rovided, so that b valve :12, t e contents willow odt, and should any solid matter rema' in the tank,- it ma be flushedout by a stream of water intro need through the inlet nip 1e 0.

What I claim as my invention 1s:-

1. A sewage stem for cars and the like comprising, the atory or thelike,

opening the a removable closed tank having means for discharging itscontents and rovided with an inlet a flexible conduit eading from thebow and separably connected with the tank-inlet and means for separablysupporting the tank from the car. 2. A sewa e system for cars and thelike comprisin e bowl of a closet, urinal, lavatory or t e like, aremovable tank having ,an inlet separabl connected with the outlet ofthe bowl, or t e like, and provided with guide lugs, and strapssuspending the tank rom the car with t eir lower members extending throuh said guide lugs, said stra s having hinge sections to permit of t eready removal of the tank. 7

3. A tank for car sewage systems, provided with a removable'head, aninlet, a vent, and guide lugs on its lower side.

In testimon whereof I aflig my signature, in presence 0 two witnesses.
